you wont find any major brand mechanical keyboard for that price, let alone one with macro keys.
-the ducky zero is about $86 but is barebones without macro keys.
-corsair k90 is $140 but does have macro keys
-corsair k95 is $150 but does have macro keys
-logitech g710+ is $150 but does have macro keys
its even hard to find a decent gaming keyboard for that price
-logitech g15 is $80 but does have macro keys (but only just a few)
-logitech g110 is $80 but does have macro keys
-logitech g510 is $110 but does have macro keys

microsoft sidewinder x4 for $50
